Received: 17 Dec 2012 – Published in Atmos. Chem. Phys. Discuss.: 13 Mar 2013 Abstract. Air quality over Europe using Models-3 (i.e., CMAQ, MM5, SMOKE) modelling
system is performed for winter (i.e., January 2006) and summer (i.e., July
2006) months with the 2006 TNO gridded anthropogenic emissions database.
Higher ozone mixing ratios are predicted in southern Europe while higher
NO2 levels are simulated over western Europe. Elevated SO2 values
are simulated over eastern Europe and higher PM2.5 concentrations
over eastern and western Europe. Regional average results suggest that
NO2 and PM2.5 are underpredicted, SO2 is overpredicted,
while Max8hrO3 is overpredicted for low mixing ratios and is
underpredicted for the higher mixing ratios. However, in a number of
countries observed and predicted values are in good agreement for the
pollutants examined here. Speciated PM2.5 components suggest that
NO3 is dominant during winter over western Europe and in a few eastern
countries due to the high NO2 mixing ratios. During summer NO3 is
dominant only in regions with elevated NH3 emissions. For the rest of
the domain SO4 is dominant. Low OC concentrations are simulated mainly
due to the uncertain representation of SOA formation.
